This research was conducted to study the initiation and propagation of surface crack width due to corrosion on reinforcement in reinforced concrete structures using finite element (FE) approach. Corrosion parameters, such as attack penetration and loss of steel section were used to define the relationship with the surface crack width. The objective of using numerical approach in the current study is to understand the effects of corrosion expansion on the behaviour of surface crack pattern and to validate the crack pattern with the available data. The output from the previous works was used to model specimens with different bar diameters and bar locations. The results from the finite element analyses were discussed subsequently.
